---To space jump, you have to do a spin jump (jump while pressing the over button). At the peak of the jump, press the jump button again to jump up higher. If you wait too long and start falling it will be hard to continue the space jump. It takes some practice to learn the timing and is easiest to do when you're going sideways. When trying to go up, it easiest to do it next to a wall.
